PET/MRI scans may help unravel mechanisms of prenatal drug damage
Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools. Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, whose findings are reported in the February issue of the Society of...Brain Scans Reveal How Gene May Boost Schizophrenia Risk
Clues about how a suspect version of a gene may slightly increase risk for schizophrenia* are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical. The study found that increased activity in the front of the...Researchers use brain scans to predict behavior
By peering into the minds of volunteers preparing to play a brief visual game, neuroscientists at Washington University School of Medicine in St. Louis have found they can predict whether the volunteers will succeed or fail at the game. "Before we present the task, we can use brain activity to predict with about 70 percent accuracy whether the subject will give a correct or an incorrect r...Retinal scans eyed for New Mexico show cattle
It sounds like science fiction, but New Mexico State University researchers are testing advanced eye-scanning technology on cattle as part of a national tracking system for animal health. "Retinal scans are part of a growing technological trend in cattle identification," said Manny Encinias, livestock specialist at NMSU's Clayton Livestock Research Center. "It painlessly flashes a beam of...Using brain scans, researchers find evidence for a two-stage model of human perceptual learning
Using advanced brain imaging techniques, researchers at Georgetown University Medical Center have watched how humans use both lower and higher brain processes to learn novel tasks, an advance they say may help speed up the teaching of new skills as well as offer strategies to retrain people with perceptual deficits due to autism. , the research team...Effect of Osteosarcoma predicted by scans
Researchers have been studying about the outcome of the hitech scanning technologies recently. A scan that looks at glucose uptake in a tumour shows who has a poor prognosis. Osteosarcoma is a bone tumour which affects mainly younger people. //It's an unusual cancer and one where the outcome tends to be rather unpredictable. Researchers at the University of Germany have used a technique called...Use of CT scans to detect lung cancer questioned
A new study by the researchers at the Johns Hopkins University School of Medicine in Baltimore cautioned that Computed Tomography(CT) scans may not be valuable for mass screening for lung cancer. They claimed that the harm of unnecessary testing for lung nodules detected by the CT scan that turn out to be benign,// and the costs of the scan far outweigh the number of lives saved by annual full-bo...Brain Scans Help Predict Alzheimer's Disease
Brain scans using positron emission tomography, or PET, markedly increase the ability of doctors to predict which patients will develop Alzheimer's disease as they grow older.//That's the main finding from the first large study to assess the use of PET scans in older people who complain of mild memory problems. Alzheimer's disease is a growing health problem, impacting about 4 million...PET Scans Found To Reveal Hidden Cancers
New research shows positron emission tomography scans not only detect known abnormalities in cancer patients but // may also identify new, unrelated cancers. Researchers evaluated 1,750 PET scans of patients with known or suspected cancers to determine if the scans also identify unexpected abnormalities. They identified 58 abnormalities in 53 patients. Forty-five of these abnormalities w...CT Scans Found To Increase The Risk Of Cancer
CT scans deliver much larger radiation doses to the organs than conventional X-rays. The effective dose delivered during a full-body CT scan // is nearly 100 times that of a typical mammogram. A new study shows the risk of cancer death from a single full-body CT scan is just slightly less than the cancer death risk of atomic bomb survivors from Hiroshima and Nagasaki in Japan. The study...Siemens Video: Smart Heart Scans for Athletes
